John 1:1-2 simply states this when it says
In the beginning was the Word, and the Word was with God, and the Word was God. He was in the beginning with God.
And who was the Word? Just a few verses later John clearly tells us
And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth.
John bore witness of Him and cried out, saying, “This was He of whom I said, ‘He who comes after me is preferred before me, for He was before me.’” (John 1:14-15)
Who was it that became flesh to dwell among us, the only begotten of the Father (John 3:16)? Who was it that John bore witness to? It was Jesus. Jesus existed in the beginning with God, and not just existing with God, but Jesus was God in the beginning! (He is still God today of course. )
Isaiah the prophet heard a message from God where God the Father said
Thus says the LORD, the King of Israel, And his Redeemer, the LORD of hosts: ‘ I am the First and I am the Last; Besides Me there is no God. (Isaiah 44:6)
God is the First and the Last, nothing existed before God and nothing will exist after Him, He is the first and the last. In Revelation Jesus identifies Himself as ” I AM the Alpha and the Omega, the Beginning and the End, the First and the Last.” (Revelation 22:13) The Alpha and Omega are the first and last letters of the greek alphabet, in English it would be the A and the Z. There are no letters before A, and none after Z. Jesus is the first and last, the beginning, and the end.
How is He that both God the Father and Jesus can be the first and the last? This is only possible because Jesus is God. Remember what John 1:1 said, “The Word was with God, and the Word was God.” Both are God in a complex Godhead( Trinity) , even though they are individual.

In the Old Testament God would refer to Himself as simply “I AM” (Exodus 3:14). That in itself is an awesome statement. Jesus later when talking to the Jews, told them, “Most assuredly, I say to you, before Abraham was," I AM.”” (John 8:58). Jesus is not only saying that He existed since before His physical birth on earth, but He is identifying Himself as being God, as being the " I Am ". Jesus again identified Himself as the "I AM" when He was being arrested in the garden. The soldiers asked if Jesus was “Jesus of Nazareth” and Jesus replied in such a way that the soldiers fell to the ground. “Now when He said to them, “I AM He,” they drew back and fell to the ground.” (John 18:6)
Jesus is the Creator!
When God is creating man He says “Then God said, “Let Us make man in Our image, according to Our likeness;” (Genesis 1:26). Who is God talking to here? Who is God referring to by saying “Us” and “Our”? God is not a single being but three, completely separate beings, three deities that are in the same Godhead. The Word was with God and the Word was God (John 1:1). This is an example of how Jesus did exist in the beginning.
Not only was Jesus with God in the beginning, before creation, but Jesus is the Creator. John 1:3 says “All things were made through Him, and without Him nothing was made that was made.” Jesus did not come only to die for His Father’s creation, but also His own. Isn’t this amazing? Jesus knew what He would have to go through, He knew all of the suffering He would face before He created us, yet He still choose to do so!...
How unfathomable is His love for us!
( *The "only begotten of( from) the Father" applied only to Jesus' unique incarnation--the virgin birth, not Jesus was created by God the Father in the beginning; this insight has just recently dawned on me.
See John 1:14 below, it was clearly after Jesus became flesh
( incarnation) then we beheld His glory, a glory of an ONLY Begotten from the Father.
In 4th century, Arius claimed "there was a time when the Son was not"; that is incorrect, because Jesus pre-existed His earthly birth as Son of man(God/man).*)
And the Word became flesh and dwelt among us. And we beheld His glory, a glory as of an only begotten from the Father, full of grace and truth.)
